This piece explores combinations of different types of linearly developing patterns. These patterns are of three main varieties: first, strictly linear patterns; second, linear patterns with free surface variation; and third, patterns which develop linearly in two opposing directions, either simultaneously or in alternation. These patterns are applied to the musical parameters of phrase length, pitch, register, dynamics, density, and timbre (the piano timbre is gradually transformed through the use of live electronic processing). As these simple patterns combine, the surface texture becomes complex and unpredictable, yet the clarity of the individual linear progressions provides an underlying direction at all times.
